US Patent:

20080282605, Nov 20, 2008

Filed:

May 17, 2007

Appl. No.:

11/749853

Inventors:

Lawrence N. Kremer - Woodland TX, US
Jerry J. Weers - Richmond TX, US
Jennifer D. Draper - Bryan TX, US

Assignee:

BAKER HUGHES INCORPORATED - Houston TX

International Classification:

C10L 1/18

US Classification:

44307

Abstract:

The addition of strong neutralizing amines to react with free fatty acid in biodiesel fuels that may be left from some synthesis routes can lower the total acid number (TAN) of the biodiesel fuel. Surprisingly, the strong neutralizing amines do not interfere with the biodiesel fuel itself which may be primarily fatty acid methyl esters. These strong neutralizing amines may also improve the oxidative stability of biodiesel fuels.

Donald Wolfe - Baden PA, US

Assignee:

International Classification:

C10G 29/16
C10G 29/10
C10C 3/08

US Classification:

208 45, 208243, 208244, 208247, 208249

Abstract:

Hydrogen sulfide evolution from asphalt or heavy fuel oil may be reduced or eliminated using an additive to act as a scavenger. Zinc, in conjunction with an additional metal selected from Fe, Mn, Co, Ni, Cr, Zr, when present in the form of nano-particles of an oxide, borate or carboxylate is an effective component is preventing or mitigating the evolution of hydrogen sulfide. The nano-particles may be used neat or as a dispersion. These metals may also be complexed and used in the form of a solution. Molybdenum, when used with one or both of Fe and Zn is also a useful in any of these forms for the same purpose.

Inventors:

BAKER HUGHES INCORPORATED - Houston TX, US
Ben Morgan - Sugar Land TX, US
Jennifer D. Draper - Bryan TX, US

Assignee:

BAKER HUGHES INCORPORATED - HOUSTON TX

International Classification:

C08L 95/00

US Classification:

524 68, 1062731, 524 59

Abstract:

Bitumen may be prepared by mixing at least two bitumen feed streams to prepare a bitumen product stream; analyzing the feed streams and the product stream to determine a stability index for each using a Bitumen Asphaltene Stability Index Test; and when the index value for the bitumen product stream is less than about 90% of the weighted average index value for the feed streams, modifying the product stream to achieve a stability index value that is at least 90% of the weighted average index value for the feed streams.

International Classification:

C10L 1/19

US Classification:

44351, 44388

Abstract:

A biodiesel may be prepared using an admixture of petroleum diesel and an algal derived hydrotreated renewable diesel which can be treated with petroleum diesel cold flow additives. The resulting diesel fuel may be employed even in cold climates despite the high paraffin content and high degree of saturation of the hydrotreated renewable diesel component of the fuel.

Assignee:

BAKER HUGHES INCORPORATED - HOUSTON TX

International Classification:

C08L 95/00

US Classification:

524 59

Abstract:

Additives may be used to improve certain physical properties of bitumen. The additives are prepared using a formulation comprising: a first component selected from the group consisting of (alkoxylated)-(di or tri)-alkyl phenol-aldehyde (amine) resins; α-Olefin-maleic anhydride co-polymers and grafted polymers including half ester/amide and full ester/amide derivatives; and combinations thereof; and a second component which is a synergist and selected from the group consisting of polyamines, amidoamines, imidazolines, and combinations thereof.

Assignee:

BAKER HUGHES INCORPORATED - Houston TX

International Classification:

C08L 95/00

US Classification:

524 68, 524 59, 524 69, 1062731

Abstract:

Bitumen may be prepared by obtaining an inflection point value for a mixed bitumen product stream sample, and modifying the mixed bitumen product stream when the inflection point value occurs at a ratio of less than about 2 mL of added non-solvent per 1 gram of the mixed bitumen product stream sample. The inflection point value may correlate to the stability of the mixed bitumen product stream based on the amount of added non-solvent. The mixed bitumen product stream may have or include at least two bitumen feed streams.
